# Aircraft design

MATLAB cost-function based algorithms for constraint analysis and descent, level, and climb performance analysis. Aerodynamic characteristics obtained with the APM solver (https://apm.aviumtechnologies.com/). Viscous corrections obtained via CFD with the SU2 solver.

Output from the MATLAB cost-function based performance algorithm.
